Network management transceiver function introduction:
1. Work mode adaptive. Special connection pulse protocol - Fast Connected Pulse (FLP) is used to support full/half duplex adaptive mode.
2. Elastic cache technology. When port congestion occurs on the switch, the transceiver sends the data destined for this port to the cache so that packet loss does not occur; and the latency of the high-speed device to the network when the high-speed device is interconnected with the low-speed device is reduced.
3. Remote error indication function. The transceiver with remote error indication function can detect the status of the fiber connection at the transmitting end through the remote error signal sent by the peer end.
4. Support for failover. Through the failover function, the faulty link can be quickly located to provide convenience for maintenance personnel.
System management features of network management transceivers:
1. The economical network management transceivers are located in the access network. The central office equipment can be managed centrally, and the user-end (far-end) devices are geographically dispersed. If a fault occurs, the Maintenance Engineering Department will receive a call from the user. The maintenance engineer first determines the location of the fault, determines the traffic route, and then must rush to the fault site as soon as possible. Due to other problems such as urban traffic, the maintenance speed is generally measured in hours. . This will easily lead to user dissatisfaction and reduce the operator's service quality.
If your fiber transceiver uses an in-band network management system, you can leave the house without leaving home and you can easily handle it in minutes. If the remote end fails, the NMS will automatically discover and alert you. You can remotely reset the client-side transceiver through the NMS. At this time, your users may not have called your office yet! Change, you need to reconfigure the user-end device, you can set the client-side transceiver port in your own office. The use of an in-band network management system can greatly enhance the operators' rapid response capability, reduce the daily maintenance workload and expenses of the operators, and improve the service quality of the operators. The in-band network management system provides you with a complete solution without increasing any management overhead.
2. Rate-specific fiber-optic transceivers (RateLimiting) The security of user data communications and the network operator's control over the user's bandwidth will be a problem that must be solved; using bandwidth control can enable operators to effectively control and distribute Network resources, and to a certain extent, prevent malicious attacks on the site. Since the traditional IP technology does not consider the issue of billing, the ordinary monthly subscription system is simple, but it greatly limits the interests of the operators. Now domestic and foreign operators have begun to use bandwidth-based charges instead of on-time charges. Bandwidth Control Fiber Transceivers provide you with the solution. The traditional adaptive transceiver can only set the ports to 10M or 100M. Now operators can set the upstream and downstream of the bandwidth control transceiver accurately (32K steps, from 0~100M). The operator can modify the set bandwidth at any time through the network management system and support online modification. For users who do not pay, they can turn off the bandwidth.
3. The practical remote fault detection (Front Fault Detect) optical fiber transceiver, abbreviated as RFD function, is also called LnkLos function, that is, link error transfer function. When a fiber transceiver is connected to a router, if one of the links (two quintets or two fibers from the central office router to the customer end switch) is faulty (such as broken), if the RFD function is not supported, the link error does not occur. It will be passed to the router to which the transceiver is connected. The Link light is still normal and the router will not update the routing table. Therefore, the data packet will continue to forward data along the line that has already failed, resulting in a lot of packet loss. The RFD function solves this problem for the network. After the fiber transceivers start the RFD function, any link that is faulty will be alarmed on the Link lights on both sides of the switch. The Link light of the router will go out and the router will reroute.
4. Network Management Transceivers Based on Standard SNMP Protocol, Support for SNMP Unified Network Management Platform Currently, the network management systems of fiber optic transceiver manufacturers are mostly dedicated systems, and they cannot cross-platform management. Operators urgently need a unified network management platform to manage all network equipment. SNMP is a standard network management protocol. Based on the SNMP protocol, a network management system was developed so that operators can use an SNMP network management software such as the HP-Open view to manage all network devices, including transceivers, routers, and switches.
5, support for WEB graphical management of network management transceivers support WEB-based management, WEB management methods are simple, intuitive and easy to learn, without the need to install a series of advantages such as special software, foreign network equipment basically supports Web management, and the more The less used Telent way.
The above is all about the functions and technical features of the network management transceiver. For more information, please contact us!
The function and technical characteristics of the network management transceiver
The network management transceiver adopts a master-slave management structure and supports out-of-band network management through SNMP and Web graphical and Telnet command lines, which provides convenient and reliable means for the maintenance and management of telecommunication operators. This article mainly introduces the functions and technical features of the network management transceiver.
